Designed to offer the "ultimate tablet gaming experience", Project Fiona comes with an Intel Core i7 processor and a 1280x800 multi-touch display.
It has joystick controllers attached on either side, and the unit features magnetometer and accelerometers to enable motion controls.
Razer said that other gaming tablets are suitable for casual titles, but the limited navigation and control capabilities make them "impossible for hardcore PC gaming".
"Adapted from a full featured PC gamepad, Project Fiona's integrated dual controllers coupled with its advanced multi-touch screen are designed to make complex game navigation ergonomic and intuitive without compromising on the portability of the tablet," said the firm on its website.
"You'll be able to carry out headshots and command troops in-game with ease. This first-of-its-kind PC gaming tablet with integrated dual controllers is definitely not for playing casual games about unhappy birds or zombie-killing flora."
Despite the fact that Project Fiona is a concept, Razer does plan to release the product. Reports suggest that it is targeting a Q4 2012 launch, priced under $1,000 (£650).
The company introduced the Switchblade gaming PC last year featuring a 17.3-inch LED screen and 2.8GHz i7 processor, but it has not yet been released in the UK.
